For a stock 1,7 with new valve guides is there a known inner dia specification?
Or lets say the valve stem is 7,95mm is there a clearance to the inner dia of the guide to aim for? Looking for recommendation on both inlet and outlet valve guides. Thanks /Lars S |

Thanks /Lars S The factory specs for the intake valve stem OD is 7.94 to 7.95 with the valve guide ID being 8.00 to 8.02 with a wear limit of 8.06. The exhaust valve stem OD is 8.91 to 8.92 with the guide ID of 9.00 to 9.02 with a wear limit of 9.06. You want the stem to fit in such a way as to allow no tipping |
